Several attempts were made to detect trends, real world events, news, earthquakes and others with satisfying results. However they do not perform well on finding local events such as release parties, musicians in a park, or art exhibitions. Many of the local events that were found by algorithms of existing work were not related to an event but to locations, global events, or just common words. In this paper, we introduce Event Radar, a novel local event detection method to improve the precision by analyzing seven day historic Tweet data. We estimate the average Tweet frequency of keywords per day in and around a potential event area and use these estimations to classify whether the keywords are related to a local event. The proposed scheme achieves a precision rate of 68% which is a significant improvement compared to related work that states a precision rate of 25.5%.","PeriodicalId":148667,"journal":{"name":"2012 IEEE International Conference on Green Computing and Communications","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128220919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Security forces and administrative bodies have to cooperate in order to share information, allocate resources and create the optimal response. In this paper we present a distributed simulation framework for studying security operations which take place inside an urban environment. More specifically, we model a cyber-physical system that aims at engaging malicious entities present inside a city. Our model includes the physical urban area, the participating actors and the information exchange among the participants. This design allows the evaluation of the effect of different communication patterns on the outcome of an operation. Finally, our platform allows us to investigate realistic scenarios with multiple participating actors and also gives us the opportunity to evaluate how different actor roles and responsibilities affect the overall operation outcome.","PeriodicalId":148667,"journal":{"name":"2012 IEEE International Conference on Green Computing and Communications","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129779175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is supposed that the common approach to attack modeling and security evaluation is based on modeling of a malefactor's behavior, generating a common attack graph, calculating different security metrics and providing risk analysis procedures. Key elements of suggested architectural solutions for attack modeling and security evaluation are using a comprehensive security repository, effective attack graph (tree) generation techniques, taking into account known and new attacks based on zero-day vulnerabilities, stochastic analytical modeling, and interactive decision support to choose preferred security solutions. The architecture of the Attack Modeling and Security Evaluation Component (AMSEC) is proposed, its interaction with other SIEM components is described. We present the prototype of the component and the results of experiments carried out.","PeriodicalId":148667,"journal":{"name":"2012 IEEE International Conference on Green Computing and Communications","volume":"18 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126069088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

People that we encounter and connect with around physical resources such as conferences, provide opportunities for extending our social networks from offline to online. We give a preliminary study on the relationship between the online and physical social networks in terms of the online and offline interactions (O2O) established during the conference, using a mobile social proximity-based platform called Find & Connect. We propose metrics of overlap fraction, network scale, and O2O transfer amount to quantify the O2O behavior of conference attendees. Our results demonstrate that more than half of the online interactions are included in the offline interaction network, and the offline to online transfer holds the dominant position in this bidirectional O2O transition between online and offline interaction networks. To the best of our knowledge, this is the first work to study the influence of offline to online, and vice versa, in a restricted environment using a social proximity-based system.","PeriodicalId":148667,"journal":{"name":"2012 IEEE International Conference on Green Computing and Communications","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126238627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of radiofrequency (RF) passive surface acoustic wave sensors probed by radiomodem interfaces commonly found on wireless sensor node platforms is therefore investigated in this work. This approach allows for providing sensors with virtually infinite life expectancy since no local power source is needed on the sensing site. Rather than harvesting energy from the environment, the passive sensor is loaded by an incoming RF source provided by the same RF interface than the one used for digital communication of the gathered data. Implementing such a scheme in an adhoc wireless sensor network configuration is demonstrated using a novel platform based on the XE1203F radiomodem which provides the specific interfaces mandatory to such an application. Furthermore, a measurement demonstration locating the sensing element in an oven heated to 550°C emphasizes environmental conditions in which no energy storage or battery would withstand such harsh conditions, while the wireless interrogation between the interrogation unit (reader) and the sensor removes the need for high temperature-compatible connector and electrical cable. Implementing the sensor probing algorithm as well as the radiomodem control interface in the TinyOS executive environment then provides access to all the functionalities of this portable development tool, including multi-hop data routing and dynamic ad-hoc network construction, while complying with a clear software hierarchy ranging from low level drivers accessing the hardware to user applications implemented as tasks.","PeriodicalId":148667,"journal":{"name":"2012 IEEE International Conference on Green Computing and Communications","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122890948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

BAS form a part of enterprise networks and can be utilized to gain access to a company network or to violate a security policy. Up to now, the threat of covert channels in BAS protocols was not discovered. While a first available solution can limit ``high level'' covert channels in BAS, there is no solution available to prevent covert channels on the lower level (i.e., in BAS protocols). In this paper, we present network covert storage and network covert timing channels in the network and application layer of the BACnet protocol stack to show that protocol-level covert channels in BAS are feasible. Additionally, we introduce the first means enabling a BAS to become multi-level secure on the network and application layer to prevent covert channels. We built a prototype based on the BACnet firewall router (BFR) to implement multi-level security in BACnet environments.","PeriodicalId":148667,"journal":{"name":"2012 IEEE International Conference on Green Computing and Communications","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123982933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
